Strange triangle shaped object photographed in Manhattan

9-17 MANHATTAN NEW YORK CITY
The event occurred last Saturday 9-17 in the early afternoon. I was taking digital photographs from the roof terrace of the new Museum located on Bowery in Manhattan’s Lower East Side. I was shooting a series of images of the downtown Manhattan skyline to get some pictures of the Freedom tower construction. Because I had no tripod I was shooting at a very fast exposure rate 1/500th of a second. In addition I was shooting in continuous mode at a frame rate of about 4 Frames per second.

I took my pictures and left the location. Last night upon looking at the images, I noticed a diamond-shaped object moving very close to the horizon in four frames of my images. On closer inspection I notices what appeared to be regular markings and windows on the craft. I had to be moving at an incredible rate of speed for it to have moved as far as it did give the frame rate it was captured at. It seems to be faintly emitting both blue and red light from the openings on it’s back area.

A helicopter was also present in the nearby vicinity. At first I thought it was a flag or something, but soon realized there was no flag pole and from frame to frame its shape stays regular. I’m hoping an expert in this type of thing can help me to rule out any other possible explanations for what they think this might be. Please contact me A.S.A.P. as I am curious to get another opinion, especially an expert one. The three images I have supplied are lower resolution details of the actual four images that were taken as described above.

Alien X Files Notes: Kind of looks like a newspaper. Not that NY is known for trash all over the place or anything.
